MLewis - this is my guessing in answer to your question about why this happens - It is my feeling that it has to do with what the plant is treated with while in production. The ones that I have had do this always seem to be ones I've bought from big box stores or nurseries that are using the same plant suppliers. I could be wrong but I do suspect it has something to do with it. Also it really is a pretty sight to have even the offsets blooming. Agree with Lynn, look for offsets that aren't blooming and remove them and replant.
I have done the 'surgery' thing many times, I figure what have I got to lose
I am not sure why some offset and others don't. It is always a surprise to see the new offsets from the blooming out semp! I think the surgery works best if you catch the plant as early in the blooming process as possible, I'm sure its a chemical thing.
